Guangde Rocket Launch Site (simplified Chinese: 广德火箭发射场; traditional Chinese: 廣德火箭發射場; pinyin: Guǎngdé Huǒjiàn Fāshè Chǎng)[1][2] also known as Base 603 (603基地)[3] is a suborbital launch site that was operated by the Chinese Academy of Sciences located in Shijiedu (誓节渡), Shijie Town (誓节镇), Guangde County, Xuancheng Prefecture, Anhui province on the Chinese east coast.[4]
The location of the site was surrounded by mountains in four directions, with no roads and no access to resources, but chosen as an upgrade to the too limited facilities of Nanhui Launch Site.
